In a current project, we've used the TreeListView to display hierachical data (sreenshot attached).

What we want to do is to expand all lines of a specific level.
For example (see screenshot) :
 > when the user clicks on button "1", all "level 1" lines should expand
 > when the user clicks on button "2", all "level 1 and 2" lines should expand
etc.

We've succeeded doing this scenario with a Style Selector (already used for background coloration) :

<styleSelectors:ConditionalStyleSelector.Level1Style>
     <Style TargetType="telerik:TreeListViewRow">
          <Setter Property="Background" Value="#6699FF" />
          <Setter Property="IsExpanded" Value="{Binding Path=IsExpandedLevel1, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Mode=TwoWay}" />
     </Style>
</styleSelectors:ConditionalStyleSelector.Level1Style>

However, when the user collapses one "level 2" line (for example) all "level 2" lines are collasped.
So we've changed the binding mode to "OneWay" :

<Setter Property="IsExpanded" Value="{Binding Path=IsExpandedLevel1, RelativeSource={RelativeSource AncestorType={x:Type UserControl}}, Mode=OneWay}" /> 

However, with mode "OneWay" it doesn't work ...

Any idea ? Or sample code to do this ?

Hi,

I hit the captioned issue that Drop Down of RadComboBox is Going to the Top Left Corner of the Screen.
It's does not happen all the time, but sometimes it does happen.

Is there any way to solve this?

Thanks

I'm evalulating Rad Charts as a possible component for my company and seem to have hit a wall.  Is it possible to have a bar chart, with positive and negative values on the same series and have the x-axis held at zero?  This would be very common in the financial world for say a performance chart.  Some bars go up, some bars go down depending on positive and negative performance buckets.  Am I correct in thinking the product does not currently support this?  

Many thanks,

Hi!

Please advice me on how can I customize the weekinterval so that it starts from Wednesday of a week and to end to Tuesday the next week (in my company the operational weeks are formed this way).
I have a table in which these weeks are kept.
If there'e a way I can bind TimeBar to this table, I will be glad to receive some help.

I attached a capture with the intervals and the selection made using my weeks table (you will see selection slightly shifted to capture those mentioned above)

Thank you in advance!

Hi,

I am having an issue with styling MapPolygons. I am able to style some settings such as the tooltip but am unsuccessful in styling other aspects like the border.

What I am trying to do is apply an Effect to a MapPolygon when the mouse is over it. Below is a Xaml snippet of my style, which doesn't work with or without the trigger. 


Applying a BorderBrush in the style doesn't work either. Is there something I am missing?

Thanks in advance.

Hello,

I am using WPF Controls version 2009.2.904.35.

First issue: I have a GridView control inside a TabItem. Whenever the application loads, if I expand the rows of the GridView control, the expansion works and the child rows are displayed. However, if I first click trough the TabItems and come back to expand the Grid rows, then the expansion works but the child rows are not shown. If I have expanded the rows at least once before I tab through, the child rows continue to be displayed even after I have visited other tabItems; the problem seems to happen only when I tab through before ever expanding any rows. One more thing, if I expand let's say 3 rows out of 5 in the grid, then tab through, then come back to expand the other 2 rows, those 2 rows' children won't be shown, but the children of the other 3 pre-expanded rows do continue to show. If I sort or filter the grid, then the rows reappear.

Second issue: If I position the cursor in between two columns to drag and size, the sizing of the column jumps around, and i can make it smaller but not bigger; also, if I stop dragging (release the mouse button), the column sizing continues to happen while I move my mouse. This happens in the same grid that's having the first issue. I have another grid in another tabItem and that one does not have the sizing issue; it also does not have child rows so I don't know if it would be the same problem.

Thanks,
Laura

Hello Telerik,

I wanted to customize GridViewSelectColumn styling. I got a reference of the GridViewSelectColumn appearence in one of the forums mentioned below:-
http://www.telerik.com/community/forums/silverlight/gridview/gridviewselectcolumn-appearnace.aspx

The issues that I am facing:-
1. If I use this above mentioned link styling then it applies to all the checkboxes in the Application not just the GridViewSelectColumn checkbox. Can you please let me know how do I apply the styling only for the check boxes in the GridViewSelectColumn?
2. Or How do I get a reference to the GridViewSelectColumn checkbox so I can apply the styling explicitly?
3. Or If its possible can you please provide the detailed style template for GridViewSelectColumn?


Thanks,
Neha

Hello,

After upgrading to Q1 2010, I've noticed that pressing enter while editing a cell commits the edit, then moves focus to the row below, putting the cell in that row into edit mode. I can certainly see why this is desirable behaviour for some applications, however, for ours it is not. Can never please everyone :). We would like to keep the behaviour from the previous version, which would commit the edit, end edit mode in the cell, and leave focus on that cell.

Is there a way to achieve that behaviour in the new version? We need to use the new version of the grid as it contains other fixes we need.

Thanks

Would it be possible to have an empty row at the start of the grid which functions as a filter? I think this would be a nice possibility for the user to have fast access to filtering.

It seems as though the access level for ColumnFilterDescriptor was changed in the latest internal build.
Can no longer access this property to save the datagridview settings for the column filter.
